The solar electroflotation (EF) processes using saline electrolytes are today one of the great challenges for development electrochemical devices, due to corrosion problems that generated during operation by being in permanent contact with Cl- ions. This manuscript discloses behavior titanium electrodes a superposition model based on mixed potential theory and evaluation superficial performance Ti operated 4 V/SHE solution 0.5 M NaCl. Additionally provided is an analysis regarding HER, ORR,...
Response surface methodology (RSM) is one of the most effective tools for optimizing processes, and it has been used in conjunction with Analysis Variance (ANOVA) test to establish effect input factors on output factors. However, when this mineral flotation, its polynomial model usually performs poorly. An alternative use artificial neural networks (ANNs) such situations. Within context, ANOVA not best option these types; moreover, requires statistical assumptions that are difficult satisfy...
The presence of ultrafine clay particles that are difficult to remove by conventional filtration creates many operational problems in mining processing systems. In this work, the removal suspensions has been investigated using an electroflotation (EF) process with titanium electrodes. results show EF is a viable and novel alternative for removing kaolinite-type present sedimentation tank overflows low salt concentrations (<0.1 mol/L) copper facilities based on saline water splitting concept....
This study demonstrates the effects of a potassium propyl xanthate (PPX) collector and sodium sulfite (Na2SO3) depressant on pure chalcopyrite in synthetic seawater (SSW) chloride (KCl) solutions. SSW solutions with 35 g/L salt 0.01-M KCl were used for microflotation zeta potential tests. Particles sized between 200# 100# (75–150 µm) used, pH was 8.0 8.5. The surface mineral its interaction characterized using Raman spectrometry. measured solution at range 3–12 monodispersed particle size...
The effect of Na2SO3 as a pyrite depressant in NaCl and KCl saline media the presence kaolinite were evaluated by zeta potential tests.Chalcopyrite was also included study, because usually accompanies this mineral.Subsequently, floatability results both minerals solution optimized based on design experiments (DoE).The Box-Behnken DoE applied considering percentage (X1), collector dose (X2), (X3) factors.The modeled using artificial neural networks (ANNs) to construct contour plots determine...
